We build AI agents that can reason and code—imbuing computers with intelligence and human values so they can help us accomplish larger goals in the world. To do this, we train foundation models optimized for reasoning. We aim to rekindle the dream of the *personal* computer—for computers to be truly intelligent tools that empower us, giving us freedom, dignity, and agency to do the things we love.

We support kind and capable founders in doing their life’s work. We try to be the investors we'd want on our own cap tables. This means we move fast, don't care who else is investing, and proactively support our founders.If you are (or plan to be) starting something you believe in, drop me a line!

Very early angel investor in Lambda School, Synthesis School, Gather.town, Roam Research, Tinycare, AssemblyAI, etc.

Accelerating human progress by making it easier to build great teams. YC S17. Sourceress was an AI sourcer that helped you automatically find and reach out to great candidates. Raised $13M from YC, Lightspeed, and DFJ.

First member cohort.

Built a laser raster display for a super high resolution virtual reality headset.

Ran company planning, exec meetings, and many special projects. Gained incredible context around how to run a fast-growing, multi-billion dollar company. Left Dropbox in good hands, and started my own.

One of the first PMs on Dropbox for Business, and then the Growth team, working on user acquisition, engagement, and retention. Launched features that increased Dropbox's monthly signup run-rate by 20%, globally.

Co-authored Sew Electric, a book that teaches computer science to middle and high school students through computational textiles (sewable fabric circuits) using LilyPad Arduino. Sew Electric is offered on Amazon, at the San Francisco Exploratorium, and in a variety of schools and summer camps across the US.Sew Electric was also one of the primary partners in Google's Made with Code initiative. Learn more at www.sewelectric.org and www.madewithcode.com/resources.

Wrote a computer science curriculum combining craft and technology to appeal to a more diverse demographic, taught through computational textiles projects using LilyPad Arduino. Curriculum is used in middle school programs including the i2 STEM Summer Camp (www.i2camp.org), Girl Scouts, Intel Computer Clubhouse, and the Craft Technologies course at Utah State University.Published the curriculum as a book (Sew Electric), available on Amazon and at the Exploratorium.

Worked with the Lilypad Arduino to create Soundie, a touch-sensitive musical hoodie. Featured in Make Online: http://gadgets.boingboing.net/2009/06/16/touch-sensitive-hood.html.

Researched high-frequency predictive quantitative signals in equity index markets. Explored and improved predictive quality of signals in R using machine learning and statistical methods.

Built automation framework for commodities electronic market-making, to allow both back- and forward-testing research, and running of actual automated strategies. Researched signal for commodity index trading; processed noise out of price data in order to improve signal accuracy.
